How to Loop Audio Files in OBS for a Nonstop Nature Stream

A single nature recording can repeat in OBS with a Media Source and its Loop setting enabled. If you have several recordings, use a VLC Video source, add the files to its playlist, and enable Loop Playlist.

The important details are easy to miss: VLC must be installed for a VLC source, its architecture must match OBS, and source visibility settings can stop or pause playback. These settings create a repeatable playback method, but OBS documentation does not guarantee gap-free operation for every 24/7 broadcast.

Choose one file or a playlist

Start by deciding whether the stream needs one recording repeated or a sequence of recordings. The choice affects the source you add, the software required, and how much you need to check when a file changes.

Your audio setup	OBS source	Extra software	Playback control
One file, such as a long forest recording	Media Source	None beyond OBS	Enable Loop
Several files in an ordered sequence	VLC Video	VLC Media Player	Enable Loop Playlist
Several files in a random sequence	VLC Video	VLC Media Player	Enable Loop Playlist and Shuffle Playlist

A Media Source is the simpler route for one file. It keeps the configuration close to the file itself, with a separate Loop option in the source properties. This is useful when your stream has one long rain recording, one birdsong track, or a single prepared audio bed.

A VLC playlist is more suitable when you have separate dawn, river, wind, and woodland recordings. You can add them together, preserve an intended order, or use shuffle when repetition in a fixed sequence would be distracting. The playlist approach adds a VLC installation and another set of playback behaviours to check.

Neither workflow requires extra hardware for the documented setup. A USB flash drive can be useful for moving or keeping local audio files, but it is not part of the looping mechanism. Keep the working files somewhere that remains available to the computer running OBS, rather than on a removable drive that might be disconnected after setup.

If the stream is intended to accompany devotional music or spoken content rather than nature recordings, the same distinction still applies. A Tamil devotional radio station on YouTube Live may have many separate tracks, while a nature loop may be built from one long file. In both cases, choose the source based on the number of files you need to manage.

Loop one file with a Media Source

For one audio file, add a Media Source to the scene that will be live.

1. Open the scene where the nature stream will run.
2. In the Sources box, add a Media Source.
3. Give the source a clear name, such as Forest audio or Night rain.
4. Select the local audio file.
5. In the source properties, turn on Loop.
6. Confirm the source and check that the audio appears in the mixer.

OBS describes Loop as making the file play again after playback has completed. It is the setting that repeats a single file. Do not confuse it with Close file when inactive, which is a separate option concerned with unloading the file when the source is hidden or not on the current scene.

For an audio-only source, the source may not have a visible picture to show in the preview. That does not by itself mean the audio is missing. Watch the mixer meter while the file plays and use the Advanced Audio Properties window to confirm that the source is routed to the stream rather than muted or excluded.

Keep the Media Source in the active scene. If you switch to another scene without that source, its behaviour may change according to its inactive-source settings. A source that is not visible or not part of the current scene is not the same as a source that is visibly playing in the scene you are sending to YouTube.

The Media Source guide from the OBS Project lists MP3, AAC, OGG, and WAV among the supported audio types. Treat that as documented source support, not as a guarantee that every file using one of those extensions will play correctly. An extension does not describe every detail of an encoding, and a damaged or unusual file can still fail to load, stop early, or behave differently from another file with the same extension.

For this reason, use the exact file you intend to stream during your test. Do not test one short MP3 and assume that a different WAV or a batch of converted files will behave identically.

Set up a VLC playlist

Use a VLC Video source when the stream needs multiple audio files. The name can be misleading: the source is not limited to video. OBS describes it as accepting video and other media files, including audio files in a playlist.

First install VLC Media Player if it is not already installed. Then check the architecture before adding the source. OBS states that 64-bit OBS requires 64-bit VLC. A mismatch can prevent the VLC source from working even though VLC itself opens and plays files normally.

Once VLC is available:

1. Open the scene that will carry the stream.
2. Add a VLC Video source.
3. Open the source properties.
4. Add the nature recordings to the playlist.
5. Arrange the files in the order you want, if order matters.
6. Leave Shuffle Playlist off for a predictable sequence, or enable it if random playback is intended.
7. Turn on Loop Playlist.
8. Apply the settings and watch the mixer while the playlist runs.

The files do not need to be combined into one long recording for this method. That makes it easier to replace one recording or add a new sound without editing the whole programme. It also creates more points to check: each file must be readable, each path must remain valid, and the transition between files should be tested.

A predictable order is usually easier to supervise. For example, you might place a short dawn recording first, followed by flowing water, light wind, and a longer night ambience file. Shuffle can make the stream less repetitive, but it makes the next item less obvious when you are diagnosing a problem.

If the stream is part of a wider 24/7 channel, keep a written list of the files and their intended order. This is a small operational habit, but it makes it easier to identify a missing file after you move the project to another computer or rebuild the scene.

Enable playlist looping and understand visibility

Loop Playlist controls what happens when the VLC source reaches the end of its media files. With it enabled, the source starts the playlist again rather than stopping after the final item. This is different from Shuffle Playlist, which changes the selection order but does not, by itself, tell the source to repeat the playlist.

For a fixed sequence, leave Shuffle Playlist off and enable Loop Playlist. For a random sequence, enable both settings. Make that choice deliberately. If you are matching a visual sequence, spoken introduction, or daily schedule, random order can put the audio out of step with the picture.

Then check the VLC source's visibility behaviour. Depending on the OBS version and source properties, you may be able to choose whether the source:

• stops when it is not visible and starts again when it becomes visible
• pauses when it is not visible and resumes when it becomes visible
• continues playing even while it is hidden

Use the behaviour that matches your scene design. If the source should continue as the audio bed while you change a visual overlay, stopping it on every visibility change may introduce a restart. If the source belongs only to one scene, stopping or pausing it when hidden may be more appropriate.

The practical choice depends on what “hidden” means in your layout. A source can be hidden because you clicked its eye icon, because another scene is active, or because the source is not part of the scene currently being output. Test the exact scene changes you expect to make during the broadcast.

A single Media Source has its own Close file when inactive setting. OBS explains that this unloads the file when it is hidden or off the current scene and can cause a short delay when it is loaded again. It is not the single-file loop control. Leave the separate Loop setting responsible for repeating the file, and decide on Close file when inactive based on how you want the source to behave between scene changes.

This is also why a source may appear to have “stopped looping” when the real issue is visibility. First check whether the source is active and whether the mixer is moving. Then inspect the relevant visibility or inactive-source setting before replacing files or rebuilding the scene.

Check VLC installation and source visibility

If a VLC Video source is empty, silent, or missing from the expected behaviour, check VLC before changing the playlist. OBS requires VLC to be installed for this source type. Installing VLC only after creating the scene may mean that the source cannot load correctly until OBS is restarted or the source is refreshed.

Check these points in order:

1. VLC is installed on the same computer as OBS.
2. The VLC architecture matches OBS. For 64-bit OBS, use 64-bit VLC.
3. The playlist contains the intended local files, not paths from another computer.
4. The files still exist at those paths.
5. The source is present in the active scene.
6. The source is not hidden by the eye control or scene layout.
7. The source is not muted in the mixer.
8. The source is included in the stream's audio output.
9. The selected visibility behaviour matches the way the scene is being used.

You can use the OBS Sources Guide to check how sources belong to scenes and how media sources fit into the OBS layout. The guide explains the source model, while the Media Sources page covers the playback controls themselves.

Do not assume that VLC being installed is enough. The VLC Video source still depends on the correct architecture, valid file paths, and the source being active. Conversely, do not install VLC merely because you are using a single Media Source. The one-file workflow does not require a VLC playlist.

For a long-running channel, keep the OBS project and audio files in a stable local location. If you rename a folder, move a recording, or change the account that runs OBS, the source may retain a path that no longer works. Make path changes while the stream is offline and confirm playback again afterwards.

A local OBS setup also leaves the computer responsible for running the application, keeping the source available, and maintaining the stream connection. If your priority is removing the need to leave that computer switched on, StreamNeo turns an uploaded video into a YouTube-only 24/7 live stream after you provide the file and stream key, with monitoring and automatic restart when the broadcast drops. That is a different operating model from configuring local playback in OBS, so decide whether you want to maintain the desktop setup or move the finished programme elsewhere before you prepare the final workflow.

Treat formats and rights as separate checks

OBS's documented list of audio types is useful when selecting a file, but it should not be read as a promise that every encoding works. MP3, AAC, OGG, and WAV are listed by OBS as supported audio types. Files with those extensions can still differ in codec details, sample properties, metadata, or file integrity.

If one file fails, compare it with a known-good file and test the original in a normal media player. Re-encoding may help with a damaged or unusual file, but it changes the file you are using and should be followed by another OBS test. Do not replace a working playlist merely because one item has a different extension, and do not assume that changing the extension will convert the audio.

Playback compatibility is also separate from permission to rebroadcast. OBS being able to open a recording does not show that you have the right to use it on YouTube. Nature recordings may belong to the person who made them, a library, or a licence holder. Check the licence for every recording and review the current platform terms before starting the public stream.

The same applies to recordings labelled “royalty-free” or “free”. Those descriptions can have conditions about attribution, commercial use, edits, territory, or redistribution. Keep a copy of the licence information with the source files so that you can identify what each recording permits. Do not describe an audio file as cleared solely because it plays in OBS.

If your channel combines nature audio with devotional music, news, or spoken material, document the rights for each part separately. A visual background and an audio track can have different owners and different conditions. The guide to streaming copyright-free Indian music 24/7 on YouTube is relevant to that broader question, but it does not replace checking the licence for the particular recording you plan to use.

Test playback through the repeat point

Do not begin with a public 24/7 broadcast. Build the scene, then test the point where the file or playlist should repeat.

For one file, start playback and note its position near the end. Let it reach completion and confirm that the same file starts again. Watch the mixer across the transition rather than checking only the preview. If you hear a gap, click, or unexpected silence, first determine whether it comes from the recording itself, the source setting, or the way the audio is routed.

For a playlist, let the final item finish and confirm that the first item returns. Also test the transition between two ordinary items in the middle of the list. A playlist can loop correctly while one individual file fails to load, so testing only the final repeat point is not enough.

Change scenes during the test if you expect to use several scenes during the broadcast. Hide and show the VLC source, switch away from its scene, and return to it. Observe whether it stops, pauses, resumes, or continues according to the setting you selected. Repeat the same check for a Media Source if Close file when inactive is enabled.

Before going live, check the audio mixer, the stream output, and the YouTube preview. A moving local meter confirms that OBS is receiving audio, but it does not by itself confirm that the correct track is being sent to the live output. If you use monitoring, remember that your local monitoring experience can differ from what viewers receive.

Write down the final configuration: source type, file or playlist location, Loop or Loop Playlist status, Shuffle status, VLC architecture, and visibility behaviour. This gives you a short recovery checklist if the stream is rebuilt after a computer update or a file move.

If a visual loop also ends unexpectedly, the cause may be separate from audio playback. The troubleshooting steps in How to Fix a YouTube Live Stream That Stops When a Rain Video Ends can help you examine the broader scene and broadcast workflow.

OBS documents how these source controls are intended to work, not a guarantee that a particular machine, file, operating system, or network will run without interruption all night. For a local setup, plan for the computer, power, storage, OBS process, and internet connection as well as the loop setting itself.

FAQ

Can I loop an MP3 in OBS without installing VLC?

Yes. Add the MP3 as a Media Source and enable Loop in its properties. VLC is needed for the VLC Video playlist workflow, not for every Media Source.

Why does my VLC playlist stop when I change scenes?

Check the VLC source's visibility behaviour. It may be set to stop when hidden, pause when hidden, or continue playing while hidden, so changing scenes can affect playback according to that setting.

Does Loop mean every audio encoding will work?

No. OBS documents support for audio types including MP3, AAC, OGG, and WAV, but that is not a guarantee for every encoding or damaged file. Test the exact recording you intend to broadcast.

Is looping audio in OBS a guarantee of a nonstop YouTube stream?

No. Loop and Loop Playlist control what happens when local media reaches the end. They do not guarantee uninterrupted operation across the computer, OBS, power, files, or network, and you should test the complete broadcast path before relying on it overnight.
